arkennemasis Catalogue Board (product x shot, Excalidraw + HTML)

ArkCatalogueBoard is how you actually see a delivered catalogue instead of scrolling a folder. It lays every delivered image out as an .excalidraw board - a row per product, a column per shot - and writes an HTML contact sheet of the same layout. The thing that makes it more than a contact sheet is what it does with missing images: it draws them as gaps rather than silently closing up. The board doubles as the run's to-do list, because "which four am I still waiting on" is the question a review board exists to answer.

It reads the CSV and the output directory, not some in-memory state, so it's always a picture of what's actually on disk. A half-finished run shows you exactly the half that's missing.

How it works

Point csv_path at the catalogue CSV, set output_dir to the same catalogue the Save node used, and choose your axes: row_by defaults to garment (one product per row) and column_by to shot (front / detail / full / back across the page). The node scans the output directory and places each found image at its grid cell; missing cells are drawn as empty outlines.

The one input that will bite you is after. It's a STRING input whose value is deliberately unused - wire Catalogue Save's path into it purely to force an execution order. The tooltip explains the trap: without the edge, the board is free to read the output folder before the images land in it, and reports a set as half-missing that was actually complete. This is the classic ComfyUI ordering problem, and the pack solves it with a dummy dependency rather than hoping the scheduler guesses right.

Useful knobs: thumb_size (0 = match the source so nothing is downsampled; set 640 or 1024 if the board is too heavy to open), write_excalidraw and write_html (both on), and board_dir (default catalogue/review).

Outputs: excalidraw_path (open it in excalidraw.com or the desktop app to annotate), html_path (the contact sheet), and report.

Installing

cd ComfyUI/custom_nodes
git clone https://github.com/Hishamahmer/comfyui-arkennemasis
pip install replicate httpx

Restart ComfyUI. No models or keys - it reads the folder and writes files.

Troubleshooting

• Board shows everything missing - you forgot the after edge, or output_dir doesn't match the Save node's. The dummy after wire isn't optional; it's the ordering fix.
• Rows/columns look scrambled - row_by and column_by name CSV columns. A typo or a renamed column produces a weird grid.
• Board is slow to open - drop thumb_size to 640 or 1024. 0 means "full-res tiles," which is beautiful and heavy.
